Systems Development Life Cycle (SDLC) or sometimes just (SLC) is defined by the as a software development process, although it is also a distinct process independent of software or other information technology considerations. It is used by a systems analyst to develop an information system, including requirements, validation, training, and user ownership through investigation, analysis, design, implementation, and maintenance. SDLC is also known as information systems development or application development. An SDLC should result in a high quality system that meets or exceeds customer expectations, within time and cost estimates, works effectively and efficiently in the current and planned information technology infrastructure, and is cheap to maintain and cost-effective to enhance. SDLC is a systematic approach to problem solving and is composed of several phases. This figure illustrates the stages in a System Development Cycle. .

Initial StudyDuring the initial stage a general analysis is done about the organization and their needs of a new system. This stage is done by a Systems Analyst, a person who will be responsible for analyzing the system. The Systems analyst will consult the users about their needs and check the backgrounds of their problems. He will produce a document which will contain his general analysis also called the feasibility report. This report will contain estimates of costs, time and benefits that would result from the system to the organization.

Systems Analysis and DesignIn this stage also the System analyst will be involved he will use the feasibility report and carry out a requirement analysis .It encompasses those tasks that go into determining the needs or conditions to meet for a new or altered product, taking account of the possibly conflicting requirements of the various people involved, such as users. It is sometimes referred to loosely by names such as requirements gathering,...

...﻿Introduction
Systemdevelopment methodologies are promoted as a means of improving the management and control of the software development process, structuring and simplifying the process, and standardizing the development process and product by specifying activities to be done and techniques to be used. It is often tacitly assumed that the use of a systemdevelopment methodology will improvesystemdevelopment productivity and quality. However, there is little empirical evidence to support this assumption. As we know that, Information System (IS) refers to a system of people, data records and activities that process the data and information in an organization, and it is includes the organization's manual and also the automated processes.
Here all the development of IS are referring to the useful of standard selection of systemdevelopment methodology. There are various types of information systems which successful implementation for the end users, for example: transaction processing systems, decision support systems, knowledge management systems, database management systems, registration system, payroll system, inventory system and office information systems. There...

“Definition - What does Software DevelopmentLifeCycle (SDLC) mean?
SDLC The software developmentlifecycle (SDLC) is a framework defining tasks performed at each step in the software development process. SDLC is a structure followed by a development team within the software organization. It consists of a detailed plan describing how to develop, maintain and replace specific software. The lifecycle defines a methodology for improving the quality of software and the overall development process.
This term is also known as the software development process.”i

„A typical Software Developmentlifecycle consists of the following stages:
Stage 1:
Planning and Requirement Analysis - Requirement analysis is the most important and fundamental stage in SDLC. It is performed by the senior members of the team with inputs from the customer, the sales department, market surveys and domain experts in the industry. This information is then used to plan the basic project approach and to conduct product...

...Homework 1: Information SystemsDevelopment Methodologies
This purpose of this paper is to give an understanding of the information systemsdevelopment methodologies available. A software development methodology or systemdevelopment methodology in software engineering is a framework that is used to structure, plan, and control the process of developing an information system. Here are some iterative methodologies that can be used especially for large projects and some of their characteristics.
Spiral Model
The idea is evolutionary development, using the waterfall model for each step; it's intended to help manage risks. Don't define in detail the entire system at first. The developers should only define the highest priority features. Define and implement those, then get feedback from users/customers (such feedback distinguishes "evolutionary" from "incremental" development). With this knowledge, they should then go back to define and implement more features in smaller chunks. Each iteration of the prototype represented as a cycle in the spiral. The Spiral software development model is a risk-oriented. Use the spiral model in projects where business goals are unstable but the architecture must be realized well enough to provide high loading and stress ability.

Relationships between the systemsdevelopmentlifecycle and software development methodologies will be detailed. The phases in the SDLC, including activities associated with planning, analysis, design, development, testing, implementation, and maintenance, will be reviewed. The characteristics of a well-defined project plan will be listed and described. Project manager strategies, specifically those that can be used to ensure a successful project, will be summarized. Lastly, three primary outsourcing options will be identified with the advantages and disadvantages of each explained.

Agile Software DevelopmentLifeCycle
Agile SDLC model is a combination of iterative and incremental process models with focus on process adaptability and customer satisfaction by rapid delivery of working software product. Agile Methods break the product into small incremental builds. These builds are provided in iterations. Each iteration typically lasts from about one to three weeks. Every iteration involves cross functional teams working simultaneously on various areas like planning, requirements analysis, design, coding, unit testing, and acceptance testing. At the end of the iteration a working product is displayed to the customer and important stakeholders.
What is Agile?
Agile model believes that every project needs to be handled differently and the existing methods need to be tailored to best suit the project requirements. In agile the tasks are divided to time boxes (small time frames) to deliver specific features for a release. Iterative approach is taken and working software build is delivered after each iteration. Each build is incremental in terms of features; the final build holds all the features required by the customer.
Graphical illustration of the Agile Model:
Agile thought process had started early in the software development and started becoming popular with time due to its flexibility and adaptability. The most popular agile methods include Rational Unified Process (1994), Scrum...

Introduction
SystemDevelopmentLifeCycle (SDLC) methodologies are mechanisms to assure that software systems meet established requirements (DOJ, 2000). These methodologies impose various degrees of discipline to the software development process with the goal of making the process more efficient and predictable. For the purpose of discussion in this paper, SDLC methodologies are divided into two groups (traditional and lightweight). The following introductory sections describe the problem to be investigated and the goal to be achieved. In addition, the introduction provides an analysis of the relevance of the research and discusses the paper’s five-chapter format.
Problem Statement and Goal
Traditional SDLC methodologies sometimes fall short in the new e-business software environment (Yourdon, 2000). They are often to “heavy” to keep up with the pace of e-business software development projects. In response to this problem, so called “light” SDLC methodologies have recently been developed and put to use. They are considered light because of the reduced documentation and managerial effort required. The goal of this paper is identify the strengths and weaknesses of these new lightweight methodologies and to make recommendations for their effective use.
Relevance
This research paper is relevant to the topic of SDLC. The...

...Background of the Study
An Information System (IS) is any combination of information technology and people's activities using that technology to support operations, management, and decision-making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, algorithmic processes, data and technology.
Information systems are distinct from information technology in that an informationsystem is typically seen as having an ICT component. Information systems help to control the performance of business processes.
An information system is a work system whose activities are devoted to processing (capturing, transmitting, storing, retrieving, manipulating and displaying) information. A work system is a system in which humans and/or machines perform work using resources to produce specific products and/or services for customers.
Enrollment system is the must have system in a school. When a student is enrolling for a specific course the school requires all the necessary information of the enrolees. When the school retrieves the important information from the student, the encoder now should input the details of the student in the enrollment system. In the enrollment system, the school can trace what are the standings of the students. The data of...

...traditional systemsdevelopmentlifecycle (SDLC).
Systemsdevelopmentlifecycle or software developmentlifecycle is a conceptual model. The systemsdevelopmentlifecycle describes the stages in an information systemdevelopment project (Marios Alexandrou 2011, para.1) which from begin till the end and maintenance of system.
The objectives of traditional systemsdevelopmentlifecycle are to ensure end-state solutions meet user requirement in support of business strategies goals (FrankKlucznik 2006, para.1) and provides detailed guides of all aspect of systemdevelopment or scope to managers.
Commonly, the traditional systemsdevelopmentlifecycle has 5 phases. First phase is planning which identify and analysis what to do. Second is analysis, analyse the requirement of system. Third is design the usability, detail and architectural of system. Next is implementation or programming through software testing and testing code. The last is support to maintain the system.
